albumArtCache: don't check artist-album combination again if it was not found before

Wrong variables are being checked, which prevents the next lines to be
executed.

albumArtCache: Update thumbnail after lookup

Update the thumbnail property of items so that we do the lookup only
once. This also allows MPRIS to get the URI of the media art.

Release 3.13.1
Post-release version bump
notification: Pass a tuple to variant instead of list

The serialized data for the media art should be a tuple, not a list.
This makes the update of the media art to fail if it is not found.

albumArtCache: Don't return path if doesn't exists

Since an invalid path is used by notification to know if the media art
is found, return None if it doesn't exists.

albumArtCache: Fix full retrieve of song items

Check first if the item is a song before retrieving the item's thumbnail
with full options. The old code always assumes that the item is an
album. Then use a different query to retrieve the album if it is a song.

notification: Don't lookup thumbnail

We could just use the thumbnail found by the player by connecting to
thumbnail-updated instead of looking it up again.

Also, serialize the default thumbnail on init which takes some seconds
to finish.

This removes the delay on the update of the notification when the media
art is not found.

notification: don't display dummy icon before actual thumbnail found
albumart: make a queue of albums being resolved
query: Remove unused queries

Remove count queries for albums and artists, which were used for
Load More buttons that are now gone.
query: Filter out songs that are videos or playlists

Some nmm:MusicPiece are also a nmm:Video, and all nmm:Playlist are also
nmm:MusicPiece objects. We should filter them out because videos don't
have artist and other important fields in grilo, and playlists should
be shown in the Playlists view instead.
